In this study, a newly operation-economy framework is proposed for the operation of the irrigation canals suffering from water scarcity periods. The framework is working based on maximization of the net revenue derived from the existing farming activities and economic value of water. To this end, the economic model of Positive Mathematic Programing (PMP) and the operational model of Model Predictive Controller (MPC) were employed respectively to determine the economic value of water and Water delivery to secondary farming units. Considering the existing agricultural potential at Qazvin irrigation network, the economic model computes economic value of water based on optimizing the existing cropping pattern. Consequently, the secondary farming units were ranked with regards to the corresponding economic values of water. According to the results, the secondary canals of L4 and L1 respectively with 2000 and 2180 got the first rank and L9 and L10 with respectively 1220 and 1000 IRR per cubic meters got the worst rank. The MPC operational model was minimizing the water level errors regarding the provided prioritizing by the economic model. Results show the satisfactory operation of the canal reaches so that the water delivery to the L4 and L1 canals with high economic water value is kept closer to the operational target levels. Although the main canal is operated at water shortages scenario, however, water delivery to these mentioned canals has not been affected.
